Understanding Static and Dynamic Heterogeneities in Confined Water

波士顿大学的尤金斯坦利获得了理论和计算化学项目的奖励，用于研究承压水中的静态和动态非均匀性。 这项研究涉及到一个可能的液-液相变的调查，可能会发生在一个高密度和低密度相的水在有限的空间。 这种相变对水的其他性质的影响也正在探索中。 研究活动分为两类：（i）计算机模拟，理论和实验相结合，以探索在密闭环境中过冷水的动力学和热力学性质;和（ii）一个家庭的双尺度潜力，允许探索频谱的基本行为正在研究。 这项研究是与来自世界各地的斯坦利合作者合作进行的。 这项工作预计将对我们理解有限空间中的水产生广泛的影响，例如人们期望在蛋白质内的离子通道和空腔内部找到水。

Eugene Stanley of Boston University is supported by an award from the Theoretical and Computational Chemistry program for research involving the static and dynamic heterogeneities in confined water. The research involves an investigation of a possible liquid-liquid phase transition that might occur between a high-density and a low-density phase of water in confined spaces. Implications of such a phase transition for other properties of water are also being explored. The research activities fall into two categories: (i) computer simulation, theory and experiment are being combined to probe the nature of the dynamics and thermodynamics of supercooled water in confined environments; and (ii) a family of two-scale potentials that allow the exploration of a spectrum of fundamental behaviors are being studied. The research is being carried out in cooperation with a number of Stanley's collaborators from around the world. The work is expected to have a broad impact on our understanding of water in confined spaces such as one would expect to find in the interior of ion channels and cavities within proteins.
